and has for its primary object the onidation the apof the vehicle simultaneously wi n plication of the coating on the surface to be covered.

That is to say, the present invention c0I1- templates a process wherein the yolatrle constituent of the coating composition. is subjected to intimate contact with artificial oxidizing agent, namely ozone, simultaneously with the operation which in olves the application of the coating. It is a well known fact that owing to the comparatively wide range in the volatile characteristic of enamels, paints and the like, s ome paints dry quicker than others, and in order to obtain the advantages of-a slow drying vehicle and yet reduce the time element required for this purpose, the present 1nven- 'tion proposes to intimately mix; ozone with '"ne of application in the form of a finely d ded spray, produced by forcing the paint material through a nozzle device by of ozone under pressure.

will be observed that it is proposed to bring the coating material into intimate cont-act with the oxidizing agent ozone in the discharge orifice of a nozzle 1, which may be 01'. the atomizing or other type. That is to say, it is proposed to utilize a spraying nozzle connected with a source of paint supply 2 and also by means of a connection 3 'ith a sto'age tank 4 of ozonized air, the same being supplied with ozone and air by a compressor 5 which is connected with an ozone generator 6. The said compressor pumps ozone from the generator 6 and air into the storage tank 4.

In order to apply the coating to the surface S for instance, the ozone and air under pressure is permitted to escape from the discharge orifice of the nozzle 1 to thereby draw the coating material also-through the nozzle and produce a finely divided spray of the paint mixture, whereby the minute globules ot-paint will be intimately and forcibly brought into contact with the ozonized air, at the time of application.

It will of course be understood that any type of atomizing or equivalent nozzle may be employed which may be found suitable to the requirements or" application, and it will also be apparent that the amount of ozone or other oxidizing agent utilized in :liorming the spray may be varied according to the volatile properties of the vehicle.
